NEW YORK 
New York Fashion Week brought its cutting-edge style uptown on Thursday, opening its spring-collection previews in a new location at Lincoln Center.

Gone are the tents at Bryant Park where hundreds of designers had launched runways since 1993. Instead, an estimated 100,000 buyers, editors, stylists and celebrities will visit the new home of Mercedes-Benz Fashion Week.

While most shows will still be in tents, located just southwest of the landmark fountain that usually welcomes opera and ballet lovers, the facilities (and the faux marble facade) have a feeling of permanence.

It was time for fashion to take its place at a New York institution of fine arts, said Stephanie Winston Wolkoff, a former Vogue employee who now is serving as Lincoln Center's liaison to this new community.

"Fashion designers are truly creative people. It's not just a business when it comes to these collections," she said.

Mayor Michael Bloomberg visited the site on Wednesday, taking the newly christened No. 1 "Fashion Line" subway there. The new name is temporary, lasting only through the eight days of fashion shows from designers such as Diane von Furstenberg, Zac Posen, Tommy Hilfiger, Carolina Herrera and Vera Wang.

"Project Runway" and one of its alumni, Christian Siriano, were the marquee shows on opening day.

New York Fashion Week, which extends into other neighborhoods, "creates major excitement that ripples through the city," Bloomberg said. He noted that fashion is responsible for 175,000 jobs in New York, and that the two fashion-show seasons have a $750 million impact on the local economy.

Bloomberg then reported that he bought his tie at Hermes, shirt at Paul Stuart and underwear at Bloomingdale's.

CHRISTIAN SIRIANO

Christian Siriano fans know from his "Project Runway" days that he has a flair for the dramatic, but what's winning him praise with the sometimes tough-to-please crowd at New York Fashion Week is his sense of his customer. He successfully juggled the two on Thursday.

First out on the runway was a buttery caramel-colored safari jacket with slim-fit white trousers - an appropriately luxe, chic outfit for women of many ages and many climates - while the finale gown was a bright-red, one-shoulder tulle gown that looked like a walking bed of roses.

Every look was paired with crazy platform shoes with cone-shaped heels that will be offered by the mass-market Payless.

Leather looks, especially a cognac wing-sleeve jacket and thick belt worn over a strapless organza pleated gown, were a highlight, and so were his modern treatments of metallic tweed, giraffe-print taffeta and snakelike embossing. A red-print cocktail dress with draped sleeves was a pretty, refreshing alternative to the usual little black dress.

Asymmetrical flounces - reminiscent of a pageant sash - were less contemporary, though.

PROJECT RUNWAY

Jessica Simpson took her seat as guest judge at Thursday's "Project Runway" show at New York Fashion Week in a super-short, sparkly silver minidress, but she had nothing on the models, who wore an extraordinary number of hot pants.

Ten aspiring designers showed their collections to Simpson, Heidi Klum, Michael Kors and Nina Garcia, although several knew they already didn't make the cut and won't be the Season 8 winner. Extra designers needed to participate to keep secret the winners and losers of episodes that haven't yet aired on Lifetime.

Opening the show, Klum, wearing a bright red menswear-style pantsuit and blouse, said she was particularly fond of this group. "I have never gotten so emotional or attached to the designers."

She promised the audience, which included singer Jordin Sparks and designer Betsey Johnson, that they'd see color and fantasy on the catwalk. The crowd also saw an uneven mix of runway-ready, masterful looks and gimmicky ones - especially those micro mini shorts that don't typically garner the best reviews when top-tier designers bring them back.

Johnson said she saw "sparks of talent" among the designers when she judged a challenge to turn party supplies into wearable clothes. "It was not up my alley, but there definitely was talent."

RICHARD CHAI

Richard Chai was feeling the vibe of Lincoln Center, turning out a spring collection for his Love label that mimicked styles favored by professional dancers and the students at the Juilliard School.

Layers, hardly new as a trend, were tweaked and freshened with sheer, sand-colored underpinnings, ribbed cummerbunds and soft, silky running shorts with contrast piping. The silhouettes were loose and flowy, but decidedly feminine thanks to the soothing neutral palette and strategic draping.

In his notes left for the stylists, editors and retailers, Chai quoted Martha Graham: "All that is important is this one moment in movement. Make the moment important, vital and worth living. Do not let it slip away unnoticed and unused."

Loose leggings were worn under shorts and dresses as the new take on tights, and a silk-poly-metal fabric blend used for jackets and a pair of chic trousers was stiff yet slouchy. Chai also brought back the wide-leg palazzo pant, an easy choice for a warm-weather vacation, often pairing it with an appropriately crinkled jacket or gathered top.

This could be a further evolution of the trouser trend that has taken hold among the fashion-forward set for fall.

VENA CAVA

The Vena Cava girls took a tour through the '80s with inspiration from Memphis, an Italian design movement dating back to the 1980s known for bold colors and geometric shapes.

Designers Lisa Mayock and Sophie Buhai showed a collection heavy on black, red, aquamarine green, rust and bright yellow. Beige culottes were paired with a black zip-up jacket. Netting was used on the back of a beige romper and on a cream cotton dress, tied with a rope belt and worn under a beige blazer.

"They are almost like disco silhouettes, some of them. They're clothes that you could just dance all night in, that you feel totally comfortable doing anything in," said Mayock.

Some dresses had asymmetrical hemlines: longer on the sides and short in back and front.

"We also have a lot of day gowns. We are kind of sick of seeing of the LBDs (little black dresses). We liked the idea of girls wearing floor length things really casually," Buhai said.
